Description

Technical Field

[0001] The present application relates to the field of optical elements, and in particular, to an optical imaging lens. Background Art

[0002] As the technological capabilities of portable electronic devices continue to improve, and the lenses they incorporate are constantly upgraded, the demand for mobile photography is growing. Smartphones are currently trending towards thinner and lighter, which requires a shorter overall length for their front-facing lenses. However, thinness and lightness are inversely correlated with image quality. As we all know, the quality of a lens's image depends not only on the number and size of pixels on the chip, but also on the number of lenses: the more lenses, the better the image quality. This increase in the number of lenses places higher demands on the module's precision and consistency, as well as on every aspect of the process, leading to a non-linear increase in technical difficulty. The trend toward thinner and lighter phones requires lens manufacturers to make lenses as thin as possible, placing even higher demands on technology and craftsmanship. Therefore, designing a compact, low-distortion, six-element optical imaging lens suitable for portable electronic devices is of great practical significance. Summary of the Invention

[0035] For a better understanding of the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely descriptions of exemplary embodiments of the present application and are not intended to limit the scope of the present application in any way. Throughout the specification, the same reference numerals refer to the same elements. The expression "and / or" includes any and all combinations of one or more of the associated listed items.

[0036] It should be noted that in this specification, the terms "first," "second," "third," etc., are used solely to distinguish one feature from another and do not limit the features. Thus, the first lens discussed below could also be referred to as the second lens or the third lens without departing from the teachings of this application.

That is, the shapes of the spherical and aspherical surfaces are not limited to those shown in the drawings. The drawings are for illustration only and are not drawn strictly to scale.

[0038] In this article, the paraxial region refers to the area near the optical axis. If a lens surface is convex and the location of the convex surface is undefined, it means that the lens surface is convex at least in the paraxial region. If a lens surface is concave and the location of the concave surface is undefined, it means that the lens surface is concave at least in the paraxial region. The surface of each lens closest to the subject is called the object-side surface of the lens, and the surface of each lens closest to the imaging plane is called the image-side surface of the lens.

[0039] It should also be understood that the terms "comprises," "including," "having," "includes," and / or "comprising," when used in this specification, indicate the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof. In addition, when expressions such as "at least one of..." appear after a list of listed features, they modify the entire list of features rather than modifying the individual elements in the list. In addition, when describing embodiments of the present application, "may" is used to mean "one or more embodiments of the present application." And, the term "exemplary" is intended to refer to an example or illustration.

[0040] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this application belongs. It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and will not be interpreted in an idealized or overly formal sense unless expressly defined as such herein.

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] The features, principles and other aspects of the present application are described in detail below.

[0043] An optical imaging lens according to an exemplary embodiment of the present application may include six lenses having optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. These six lenses are arranged sequentially along the optical axis from the object side to the image side. Any two adjacent lenses among the first through sixth lenses may be spaced apart by a distance.

[0044] In an exemplary embodiment, the first lens may have positive optical power; the second lens may have negative optical power; the third lens may have negative optical power, with its object-side surface being convex and its image-side surface being concave; the fourth lens may have negative optical power, with its object-side surface being convex and its image-side surface being concave; the fifth lens may have positive optical power, with its object-side surface being convex and its image-side surface being convex; and the sixth lens may have negative optical power, with its object-side surface being concave. This surface configuration of the optical imaging lens facilitates a more reasonable distribution of optical power within the optical imaging lens without oversizing the lens, which is crucial for improving the aberration correction capability and reducing the sensitivity of the optical imaging lens. This not only improves the imaging quality of the optical imaging lens, but also reduces the overall length of the optical imaging lens, ensuring its ultra-thin nature.

[0045] In an exemplary embodiment, the optical imaging lens according to an exemplary embodiment of the present application further includes a stop disposed on the object-side surface of the first lens.

[0046] In an exemplary embodiment, the optical imaging lens according to the present application can satisfy the following conditions: TTL / ImgH < 1.3, where TTL is the distance along the optical axis from the object-side surface of the first lens element to the imaging plane of the optical imaging lens, and ImgH is half the diagonal length of the effective pixel area on the imaging plane. More specifically, TTL and ImgH can further satisfy the following conditions: TTL / ImgH < 1.22. Meeting TTL / ImgH < 1.3 not only increases the image plane size and improves image quality, but also reduces the lens height along the optical axis, reducing space usage and enhancing the user experience.

[0047] In an exemplary embodiment, the distance TTL from the object side of the first lens to the imaging surface of the optical imaging lens on the optical axis may satisfy 4.10 mm. <TTL<4.26mm。

[0048] In an exemplary embodiment, half the diagonal length ImgH of the effective pixel area on the imaging plane of the optical imaging lens may be, for example, in the range of 3.42 mm to 3.55 mm.

[0049] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: -50.0 < f4 / (f + f6) < -35.0, where f4 is the effective focal length of the fourth lens, f6 is the effective focal length of the sixth lens, and f is the effective focal length of the optical imaging lens. More specifically, f4, f, and f6 may further satisfy: -45.2 < f4 / (f + f6) < -38.1. Satisfying -50.0 < f4 / (f + f6) < -35.0 and reasonably distributing the optical power of the fourth lens and the sixth lens is beneficial to effectively correcting the distortion in the paraxial range of the image plane, thereby improving the imaging quality of the optical imaging lens.

More specifically, TTL and f may further satisfy: TTL / f < 1.22. Satisfying TTL / f < 1.3 is beneficial to both increasing the image plane size and improving the imaging quality; and is also beneficial to reducing the height of the lens along the optical axis direction, reducing the space occupation, and improving the user experience.

[0051] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1.0 < CT1 / T56 < 2.0, where CT1 is the central thickness of the first lens on the optical axis, and T56 is the air gap between the fifth lens and the sixth lens on the optical axis. More specifically, CT1 and T56 may further satisfy: 1.3 < CT1 / T56 < 1.6. Satisfying 1.0 < CT1 / T56 < 2.0 is beneficial to ensuring the processing and forming characteristics of the first lens.

[0052] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 6.0 < f3 / (f1 + f2) < 9.0, where f1 is the effective focal length of the first lens, f2 is the effective focal length of the second lens, and f3 is the effective focal length of the third lens. More specifically, f3, f1, and f2 may further satisfy: 6.0 < f3 / (f1 + f2) < 8.8. Satisfying 6.0 < f3 / (f1 + f2) < 9.0 can reasonably distribute the optical power of the first three lenses, reduce the aberration of the optical imaging lens, and improve the imaging quality.

[0053] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 8.0 < f5×(R5 + R10) / (R9×CT5) < 11.0, where f5 is the effective focal length of the fifth lens, R5 is the radius of curvature of the object side surface of the third lens, R9 is the radius of curvature of the object side surface of the fifth lens, R10 is the radius of curvature of the image side surface of the fifth lens, and CT5 is the central thickness of the fifth lens on the optical axis. More specifically, f5, R5, R10, R9, and CT5 may further satisfy: 8.4 < f5×(R5 + R10) / (R9×CT5) < 10.7. Satisfying 8.0 < f5×(R5 + R10) / (R9×CT5) < 11.0 can reasonably distribute the optical power of the third lens and the fifth lens, reduce the aberration of the optical imaging lens, and improve the imaging quality.

[0054] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: 1.2 < CT6×R12 / (CT4×R8) < 2.0, where CT4 is the central thickness of the fourth lens on the optical axis, CT6 is the central thickness of the sixth lens on the optical axis, R8 is the radius of curvature of the image side surface of the fourth lens, and R12 is the radius of curvature of the image side surface of the sixth lens. More specifically, CT6, R12, CT4, and R8 may further satisfy: 1.4 < CT6×R12 / (CT4×R8) < 1.7. Satisfying 1.2 < CT6×R12 / (CT4×R8) < 2.0 can ensure the processing and forming characteristics of the fourth lens and the sixth lens, reduce the off-axis aberration of the optical imaging lens, and improve the imaging quality.

[0055] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy: -3.5 < f3×T23 / (CT3×R6) < -2.8, where f3 is the effective focal length of the third lens, CT3 is the central thickness of the third lens on the optical axis, T23 is the air gap between the second lens and the third lens on the optical axis, and R6 is the radius of curvature of the image side surface of the third lens. More specifically, f3, T23, CT3, and R6 may further satisfy: -3.45 < f3×T23 / (CT3×R6) < -2.5. Satisfying -3.5 < f3×T23 / (CT3×R6) < -2.8 can ensure the processing and forming characteristics of the second lens and the third lens, reduce the off-axis aberration of the optical imaging lens, and improve the imaging quality.

[0056] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy the following conditions: -4.0 < Tan (Semi-FOV) × f3 / (R7 + R9) < -2.5, where Semi-FOV is the maximum half field of view angle of the optical imaging lens, f3 is the effective focal length of the third lens, R7 is the radius of curvature of the object side surface of the fourth lens, and R9 is the radius of curvature of the object side surface of the fifth lens. More specifically, Semi-FOV, f3, R7, and R9 may further satisfy the following conditions: -3.53 < Tan (Semi-FOV) × f3 / (R7 + R9) < -2.50. Satisfying the condition -4.0 < Tan (Semi-FOV) × f3 / (R7 + R9) < -2.5 ensures that the optical imaging lens has a relatively wide photographic range, and can reasonably allocate the optical power of the third lens, the fourth lens, and the fifth lens, thereby reducing off-axis aberrations of the optical imaging lens and improving imaging quality.

[0057] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy the following conditions: 40.0 < R3 / (R1+R11) < 50.0, where R1 is the radius of curvature of the object-side surface of the first lens element, R3 is the radius of curvature of the object-side surface of the second lens element, and R11 is the radius of curvature of the object-side surface of the sixth lens element. More specifically, R1, R3, and R11 may further satisfy the following conditions: 44.1 < R3 / (R1+R11) < 49.9. Satisfying 40.0 < R3 / (R1+R11) < 50.0 is beneficial for ensuring the processing and molding characteristics of the first, second, and sixth lenses, reducing off-axis aberrations of the optical imaging lens, and improving imaging quality.

[0058] In an exemplary embodiment, the optical imaging lens according to the present application may satisfy the following conditions: -4.0 < (Fno × f2) / (R2 + R4) < -2.5, where Fno is the aperture value of the optical imaging lens, f2 is the effective focal length of the second lens, R2 is the radius of curvature of the image side surface of the first lens, and R4 is the radius of curvature of the image side surface of the second lens. More specifically, R1 and CT2 may further satisfy the following conditions: -3.9 < (Fno × f2) / (R2 + R4) < -2.8. Satisfying -4.0 < (Fno × f2) / (R2 + R4) < -2.5 can ensure the amount of light entering the optical imaging lens, and can reasonably distribute the optical power of the first lens and the second lens, thereby reducing off-axis aberrations of the optical imaging lens and improving imaging quality.

[0059] In an exemplary embodiment, the effective focal length f1 of the first lens may be, for example, in the range of 3.25 mm to 3.39 mm, the effective focal length f2 of the second lens may be, for example, in the range of -12.49 mm to -11.64 mm, the effective focal length f3 of the third lens may be, for example, in the range of -73.15 mm to -55.59 mm, the effective focal length f4 of the fourth lens may be, for example, in the range of -61.87 mm to -51.74 mm, the effective focal length f5 of the fifth lens may be, for example, in the range of 2.51 mm to 2.65 mm, and the effective focal length f6 of the sixth lens may be, for example, in the range of -2.16 mm to -2.08 mm. The effective focal length f of the optical imaging lens may be, for example, in the range of 3.44 mm to 3.53 mm. The maximum half field of view (Semi-FOV) of the optical imaging lens satisfies: Semi-FOV>44°, and the Semi-FOV may be, for example, in the range of 44.0° to 44.7°. The aperture value Fno of the optical imaging lens may be, for example, in the range of 2.34 to 2.51.

[0060] In exemplary embodiments, the optical imaging lens according to the present application further includes a filter for correcting chromatic aberration and / or a protective glass for protecting the photosensitive element located on the imaging surface. The optical imaging lens according to the above-described embodiment of the present application may utilize multiple lens elements, such as the six lens elements described above. By properly allocating the focal power, surface shape, center thickness of each lens, and on-axis spacing between lenses, the low-order aberrations of the optical imaging lens can be effectively balanced and controlled, while simultaneously reducing its tolerance sensitivity and maintaining its miniaturization.

[0061] In an embodiment of the present application, at least one of the mirror surfaces of each lens in the first to sixth lenses is an aspherical mirror surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, the object side surface and the image side surface of each lens in the first to sixth lenses are aspherical mirror surfaces.

[0062] However, those skilled in the art will appreciate that the number of lenses comprising the optical imaging lens can be varied to achieve the various results and advantages described herein without departing from the claimed technical solutions. For example, while six lenses are described in the embodiments, the optical imaging lens is not limited to six lenses. If desired, the optical imaging lens may also include other numbers of lenses.

[0063] Specific embodiments of the optical imaging lens applicable to the above-mentioned embodiments will be further described below with reference to the accompanying drawings.

[0066] like Figure 1 As shown, the optical imaging lens includes, from the object side to the image side, an aperture STO, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, a fifth lens E5, a sixth lens E6, a filter E7 and an imaging surface S15.

[0067] The first lens E1 has positive optical power, with its object-side surface S1 being convex and its image-side surface S2 being concave. The second lens E2 has negative optical power, with its object-side surface S3 being convex and its image-side surface S4 being concave. The third lens E3 has negative optical power, with its object-side surface S5 being convex and its image-side surface S6 being concave. The fourth lens E4 has negative optical power, with its object-side surface S7 being convex and its image-side surface S8 being concave. The fifth lens E5 has positive optical power, with its object-side surface S9 being convex and its image-side surface S10 being convex. The sixth lens E6 has negative optical power, with its object-side surface S11 being concave and its image-side surface S12 being concave. The filter E7 has an object-side surface S13 and an image-side surface S14. Light from an object passes through each surface S1 to S14 in sequence and is ultimately imaged on the imaging surface S15.

[0068] In this example, the effective focal length f of the optical imaging lens is 3.47 mm, the total length TTL of the optical imaging lens (i.e., the distance on the optical axis from the object-side surface S1 of the first lens element E1 to the imaging surface S15 of the optical imaging lens) is 4.11 mm, half the diagonal length ImgH of the effective pixel area on the imaging surface S15 of the optical imaging lens is 3.43 mm, half the maximum field of view Semi-FOV of the optical imaging lens is 44.1°, and the aperture value Fno of the optical imaging lens is 2.47.

[0082] Example 2

[0083] The following reference Figures 3 to 4DThe optical imaging lens according to Example 2 of the present application is described. In this embodiment and the following embodiments, for the sake of brevity, some descriptions similar to Example 1 will be omitted.

[0085] The first lens E1 has positive optical power, with its object-side surface S1 being convex and its image-side surface S2 being concave. The second lens E2 has negative optical power, with its object-side surface S3 being convex and its image-side surface S4 being concave.

The sixth lens E6 has negative optical power, with its object-side surface S11 being concave and its image-side surface S12 being concave. The filter E7 has an object-side surface S13 and an image-side surface S14. Light from an object passes through each surface S1 to S14 in sequence and is ultimately imaged on the imaging surface S15.

[0086] In this example, the effective focal length f of the optical imaging lens is 3.45 mm, the total length TTL of the optical imaging lens (i.e., the distance on the optical axis from the object-side surface S1 of the first lens element E1 to the imaging surface S15 of the optical imaging lens) is 4.13 mm, half the diagonal length ImgH of the effective pixel area on the imaging surface S15 of the optical imaging lens is 3.43 mm, half the maximum field of view Semi-FOV of the optical imaging lens is 44.3°, and the aperture value Fno of the optical imaging lens is 2.50.

Tables 4-1 and 4-2 show the high-order coefficients of the various aspherical mirror surfaces that can be used in Example 2, where the surface shape of each aspherical surface can be defined by formula (1) given in Example 1 above.

[0125] Example 5

[0126] The following reference Figures 9 to 10D An optical imaging lens according to Example 5 of the present application is described. Figure 9 A schematic structural diagram of an optical imaging lens according to Example 5 of the present application is shown.

[0127] like Figure 9 As shown, the optical imaging lens includes, from the object side to the image side, an aperture STO, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, a fifth lens E5, a sixth lens E6, a filter E7 and an imaging surface S15.

[0128] The first lens E1 has positive optical power, with its object-side surface S1 being convex and its image-side surface S2 being concave. The second lens E2 has negative optical power, with its object-side surface S3 being convex and its image-side surface S4 being concave. The third lens E3 has negative optical power, with its object-side surface S5 being convex and its image-side surface S6 being concave. The fourth lens E4 has negative optical power, with its object-side surface S7 being convex and its image-side surface S8 being concave. The fifth lens E5 has positive optical power, with its object-side surface S9 being convex and its image-side surface S10 being convex. The sixth lens E6 has negative optical power, with its object-side surface S11 being concave and its image-side surface S12 being concave. The filter E7 has an object-side surface S13 and an image-side surface S14. Light from an object passes through each surface S1 to S14 in sequence and is ultimately imaged on the imaging surface S15.

[0129] In this example, the effective focal length f of the optical imaging lens is 3.48 mm, the total length TTL of the optical imaging lens (i.e., the distance on the optical axis from the object-side surface S1 of the first lens element E1 to the imaging surface S15 of the optical imaging lens) is 4.18 mm, half the diagonal length ImgH of the effective pixel area on the imaging surface S15 of the optical imaging lens is 3.50 mm, half the maximum field of view Semi-FOV of the optical imaging lens is 44.6°, and the aperture value Fno of the optical imaging lens is 2.45.

[0130] Table 9 shows the basic parameters of the optical imaging lens of Example 5, where the units of curvature radius, thickness, and effective focal length are all in millimeters (mm). Tables 10-1 and 10-2 show the high-order coefficients of the various aspherical mirror surfaces that can be used in Example 5, where the surface shapes of the various aspherical surfaces can be defined by Formula (1) given in Example 1 above.

[0166] Example 8

[0167] The following reference Figures 15 to 16D An optical imaging lens according to Example 8 of the present application is described. Figure 15 A schematic structural diagram of an optical imaging lens according to Example 8 of the present application is shown.

[0168] like Figure 15 As shown, the optical imaging lens includes, from the object side to the image side, an aperture STO, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, a fifth lens E5, a sixth lens E6, a filter E7 and an imaging surface S15.

[0169] The first lens E1 has positive optical power, with its object-side surface S1 being convex and its image-side surface S2 being concave. The second lens E2 has negative optical power, with its object-side surface S3 being convex and its image-side surface S4 being concave. The third lens E3 has negative optical power, with its object-side surface S5 being convex and its image-side surface S6 being concave. The fourth lens E4 has negative optical power, with its object-side surface S7 being convex and its image-side surface S8 being concave. The fifth lens E5 has positive optical power, with its object-side surface S9 being convex and its image-side surface S10 being convex. The sixth lens E6 has negative optical power, with its object-side surface S11 being concave and its image-side surface S12 being concave. The filter E7 has an object-side surface S13 and an image-side surface S14. Light from an object passes through each surface S1 to S14 in sequence and is ultimately imaged on the imaging surface S15.

[0170] In this example, the effective focal length f of the optical imaging lens is 3.51 mm, the total length TTL of the optical imaging lens (i.e., the distance on the optical axis from the object-side surface S1 of the first lens element E1 to the imaging surface S15 of the optical imaging lens) is 4.24 mm, half the diagonal length ImgH of the effective pixel area on the imaging surface S15 of the optical imaging lens is 3.54 mm, half the maximum field of view Semi-FOV of the optical imaging lens is 44.4°, and the aperture value Fno of the optical imaging lens is 2.38.

[0171] Table 15 shows the basic parameters of the optical imaging lens of Example 8, where the units of curvature radius, thickness and effective focal length are all in millimeters (mm). Tables 16-1 and 16-2 show the high-order coefficients of each aspherical mirror surface that can be used in Example 8, where the surface shape of each aspherical surface can be defined by formula (1) given in Example 1 above.
